Condensation Control

condensation

Condensation is by far the most common cause of dampness in buildings, probably accounting for the majority of damp problems reported. It affects both old and new buildings, but it appears to be a significant problem where the building has been modernized.

Condensation is directly associated with mould growth. It is this that the resident notices first. The mould is usually found on decorative surfaces, especially wallpapers, where it can cause severe and permanent spoiling. In many cases, the mould and its spores give rise to complaints about health, and cause the “musty” odor frequently associated with a damp house.

dampThe obvious places for condensation to occur are on cold walls and floors, but it can also occur in roof spaces and in sub-floor areas where there is a timber suspended floor over; in the latter case, it can lead to wood rotting fungal development in flooring timbers.

Heat Recovery Ventilators

Heat Recovery Ventilators provide a continuous air change, replacing stale moisture laden air with fresh, warmed air from outside. The units are easy to fit and provide an effective solution to stale, musty indoor air, condensation and mould growth problems in any room in which they are fitted.

Unlike conventional extractor fans which remove and waste expensively produced heat; Heat Recovery Ventilators recover up to 86% of exhaust heat, even when operating on boost mode.

The continuous controlling of Relative Humidity levels ensures that conditions will not exist in which condensation or mould growth problems can develop and thrive.
Filters should be removed regularly and replaced or cleaned with a domestic vacuum cleaner or washed if exceptionally dirty.

The motors are guaranteed for 5 years and are fitted with ‘Sealed for Life’ bearings, which do not require maintenance or lubrication.

Note from the photo, the separate isolating transformer/humidity sensor control unit, including a thumb wheel to adjust the setting for the humidity level at which the fans are switched from trickle to boost mode.

A pull cord provides a manual override option to facilitate additional boost supplies of fresh filtered air.
